Be gentle to all and stern with yourself.
To know oneself, one should assert oneself.
Without hard work, nothing grows but weeds.
Be thine own palace, or the world's thy jail.
You never know what motivates you.
Wherever you are - be all there.
It's always too early to quit.
The secret of getting ahead is getting started.
If you've got a talent, protect it.
Things do not happen. Things are made to happen.
Maybe that's the whole teen oeuvre, you know covering people in disgusting bodily fluids and whatnot.
